Agent everything in your quote of satoshi suggests that he knew it would be problem if he told people it probably can't be changed in the future.  So the way he put it suggests to me he says "you COULD do this....we COULD do it....heres how we WOULD do it...." etc.

The rest is your implication.

 IadixDev, can you give me some context of your exp and knowledge/education so I can speak to what you know?
